You can use an Cisco MSE (3350) appliance for the location tracking. This integrates with Aeroscout tags fairly well.
Check the release notes for the MSE appliance:

Refer to the AeroScout Context-Aware Engine for Tags, for Cisco Mobility Services Engine User's Guide at the following link:

You need to have a location license for your WCS and then the integration is very simple with the MSE appliance.
The MSE will also let you track all the clients on the wireless network that are connected to controllers on the WCS maps.
So you will see the computers pretty much real time on the WCS maps.
